Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
electrical noise in terminal 53. A high time constant value improves dampening but also increases
the time delay through the filter.
This parameter cannot be adjusted while the motor is running.
Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the analog
outputs are used as part of a decentral I/O system (e.g. when not part of any frequency converter
related control functions, but feeding an external control system with data)
Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/

Function:
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
